Gendry

He was born to a worker in an alehouse. When he was old enough, an unknown lord paid his apprentice fee so he could learn to be a blacksmith. Jon Arryn's discovery of Gendry's heritage led him to discover that Joffrey and his siblings were not related to King Robert. After Jon Arryn's death Eddard Stark suspected a conspiracy behing Jon Arryns death which led him to Gendry and the same discovery that Jon Arryn had made. Shortly after Eddard Stark's fall, arrangements were made for Gendry leave the city, to avoid his past catching up to him, which he did in the company of Yoren, Arya Stark and others, destined for the Wall.

He is said to have very large shoulders and arms due to his work as a black smith. His overall outward appearance is said to be reminiscent of his uncle Renly Baratheon, who is said to look very much like a young King Robert.

His nickname is "The Bull" due to his precious Silver Bull's Helmet he forged himself.
